Picture of Structure
As figure 1, It adopts single indoor antenna to meet the demands of the whole indoor coverage system, which is suitable for the narrow and simply-distributed indoor space.

Notice for Installation 1. In case any interference, the indoor antenna should be installed away from the outdoor antenna, at least 5 meters 2. The indoor antenna should be installed at the corner of the 2 meters height or inversed and fastened to the ceiling. Identify the proper position for Indoor antenna. It should make the Indoor antenna looks practical and beautiful, as well as make it easy to balance the coverage of the signal. 3. In case the downsizing of the indoor signals coverage caused by the oxidation because of damp, all the joint should be sealed waterproof of tape. 4.. In order to reduce the wastage and enlarge the coverage, when in installation, the cable should be as short as possible. 5. Detect the safe direction and position with the strongest signal on the top of the building or surrounding by using the mobile phone; It would be better make it near to amplifier in order to be easily maintained; Keep the outdoor antenna away from the high frequency aerial, metal net, high voltage cable or transformer; Be aware of avoiding suffering from thunder and lightning strike. 6. Adjust the outdoor antenna, as usual, it should be fixed straightly and face the direction of the base, as illustrated in the figure. 7. Tie a circle in the cable, as illustrated in the figure 5, to avoid that the water filter into the booster through the cable resulting in short circuit.

Installation Steps 1. After identifying the position of outdoor antenna, indoor antenna and booster, Insert the joint of outdoor antenna into the port in the ?OUTDOOR ANTENNA? of the amplifier and fasten tightly. 2. Plug the end of the cable of indoor antenna into the ?INDOOR ANTENNA? of the amplifier and fasten tightly. 3. Connect with the power supply, if the indicated light is on that means the set-up is completed. Test and Adjustment Test with the mobile phone everywhere indoor. When the signal indication of the mobile phone show 3 to 4 marks (5 marks is full) at the corner of the room, which means the best receivability. Otherwise the position of the booster and indoor antenna should be readjusted. Adjust the position of the outdoor antenna until the mobile get stronger signal. If it stays the same after doing that, One has to choose another model which can achieve the bigger coverage. You can also install more pieces for bigger area.
F. Q & A 1. We could not call though signal of mobile-phone is good. Usually, that means the up-converter power is not enough or outdoor antenna didn?t aim at the antenna of telecom bureau, we can adjust the outdoor antenna or change another amplifier higher-power. 2. The signal is strong in some locations, weak in some locations. That means power is distributed unevenly due to something wrong with the inside antenna. If the signal in several positions is weak, we can distribute a line from the amplifier because too many allocations maybe lead to decrease the signal. If the signal in many places is weak, we can connect antennas by the parallel connection. 3. The signal everywhere is weak. I think that means the power of amplifier is not enough. Changing a higher one may be fine. 4. Serious disturbance Outdoor antenna and indoor antenna are so close that they take place self-excitation. We can adjust the outdoor antenna position.
